We look at the division of 915020 by 2 
Let's see how many times 2 fits into 915020.

On to step 1:
2 goes into 9 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 8 from 9 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

Moving on to step 2:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 10 away from 11, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Advancing to step 3:
15 divided by 2 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 457.0
The remainder is 1 after subtracting 14 from 15.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Advancing to step 4:
When dividing 10 by 2, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4575.0
If we take 10 away from 10, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Moving on to step 5:
2 divided by 2 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 45751.0
If we subtract 2 from 2, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Moving on to step 6:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 457510.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 457510.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 457510.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 457510.0 with a remainder of 0.0.
